Hi Mark!

howdy, sposaro!

how can I help you today?

Not really sure. Just finished up with that linting support for Phabricator and now I have to move on to unit tests. Not really familiar with Unit tests at all let along Android ones.

unit tests *of* the Phabricator support?

wouldn't those be in PHP

?

So I guess I just wanted to pick your brain and beliefs on testing structure and what now

Yeah. Well that's the end goal is run the AndroidUnitTests to create a report that will be handed off to Phabricator

**what not

given an Android project set up for command-line builds, ant run-tests will execute them in a standard JUnit test runner

and you get standard JUnit output

lol. Yeah. Guess I need to start learning JUnit, I'm only familiar with G-Unit :)

particularly if you want to get fancy (e.g., formatting output), you'll need some JUnit-fu

note that Android bakes in JUnit 3.x, not 4.x, so the annotation-based testing you'll read about that showed up in 4.x is unavailable

ok cool. I will keep that in mind. I think I remember something saying not to use 4.X

I guess I do have one question that I have been meaning to ask and it bugs me everything.

there's a chapter in _The Busy Coder's Guide to Advanced Android Development_ (and the current Omnibus) that covers JUnit in Android, though it's not one of my better chapters

ok thanks. I haven't look at any of the updates since I last taught my mobile programming class in the fall and I don't remember ever focusing on that

It there a way to horizontally center 2 views in a RelativeLayout without creating a new ViewGroup?

2 views side-by-side that is

define "creating a new ViewGroup"

a horizontal LinearLayout as a child of the RelativeLayout could do it

stuffing them into say a LinearLayout

oh

I can't think of how you'd do that

short of fiddling with margins from Java code

in which case I'd *seriously* steer you towards just using the child LinearLayout

yeah that won't scale well

???

messing around with fixed marins in dip won't look nice when I rotate the screen

oh, sorry, I thought you meant the child LinearLayout wouldn't scale well

I thought I saw Romain post something that said to use Gravity or layout_gravity somehow, but I haven't been able to get it to work

yes, manual margin manipulation makes messes

centering something horizontally in a RelativeLayout is easy, so long as it is only one thing

depending on what the two views are, you could try to have them both be truly centered and use gravity to shove their respective "content" to the left and righ

er, right

but that seems unlikely to work except in a few cases

yeah. I only every get a freebee if I can use a compounddrawable

well I guess that answers my issue, I feel better knowing that the man himself would have done the same thing, lol

unless you're running into stack depth issues, I'd start with using the nested layouts and then worry about performance if/when it becomes an issue

stack depth is the one big thing to drive people away from nested layouts

yeah. I'm pretty good at ViewOptimizations. I implemented the new favorites layout for ICS in the phone and people app and had to constantly worry about even "good enough" performance, lol

I was able to take 33 views from this one layout at work and condense it into 10.

that's impressive

They thought the background task was the problem, but traceview showed me it was onDraw and onMeasure

Traceview is definitely the tool to use for this sort of thing

do you have another question?

no. I think that's it for today

OK

Jelly Bean statue showed up at the Googleplex, so tomorrow's likely to be a bigger-than-average day...

oh cool. Did they post another youtube video?

dunno -- I got a still photo via Twitter

I'm really excited. Even more so now that I actually know many of the presenters

ha. that's great thanks

well, that's a wrap for today's chat

next one is 10am Eastern on Thursday

have a pleasant day!

ok. thanks mark
